Interesting link, thank you. I looked up the products for home use and I have three questions for you.
One, do you need the version with a firewall if your router has one and the one for WindowsXP is also on? Just trying to find the most cost-effective version.
I'm not the best person to ask about that. I do know that WinXP firewall is pretty basic so the Kaspersky one might be better as it has anti-hacker abilities (this is on the internet security suite).
Two, does the anti-spyware program block spyware before it gets to your computer?.
I'm not entirely sure. I know if you click on a link in a web page then it will alert you to the threat if it is infected with something and it will automatically delete it i think. If you are downloading an a file such as a zip then I don't think Kaspersky detects anything until it's on your computer. I'm really not too sure, sorry. You'll have to do some research on that.
Three, how is the program on resources? I don't like programs that are resource hogs or that slow down my machine.
I never notice it running in the background. I just looked at it's memory usage in processes and it's 4,588 K which is very good isn't it? CPU usage remains at 0-1% so it doesn't use much when running in the background.
When you ask it to scan your computer, my cpu usage fluctuates all over the place and mem usage increases quite fast but then goes back down. It all depends on your system though as to how much of a performance hit you get when carrying out other tasks whilst scanning doesn't it?
I remember Symantec was awful when scanning. I couldn't do anything else at all without dramatic slowdowns but Kaspersky allows me to continue other tasks but I usually let the scan run when i'm not using the computer or do very simple tasks so I think you need to try it out for yourself before you buy. It might act differently on your computer, I don't know.
